In this case, the panel member 20 may be disposed on the transfer member 160, and may be disposed on the transfer member 160 at a specific position. In addition, it is possible to remove the protective film while the protective film or the like is attached to one surface of the panel member 20. At this time, at least one of the cover member 10 and the panel member 20 may have an adhesive member 40 disposed or disposed thereon.

The transfer member 160 may be supplied in a roll-to-roll form. At this time, the transfer member 160 may be a flexible material, and a separate adhesive member is disposed on one surface of the transfer member 160 on which the panel member 20 is seated so that the panel member 20 is fixed. It is possible. In this case, the adhesive force of the adhesive member disposed on one surface of the transfer member 160 may be less than the adhesive force of the adhesive member 40.

As described above, after the cover member 10 and the panel member 20 are disposed, the roller unit 140 moves the transfer member 160 so that the cover member 10 and the panel member 20 face each other. By arranging 20), the positions of the panel member 20 and the cover member 10 may be aligned. At this time, although not shown in the drawings, a vision unit (not shown) including a camera, etc. is disposed, and the panel member 20 is based on at least one image of the panel member 20 and the cover member 10 photographed by the vision unit. ) And the position of the cover member 10, and then the positions of the panel member 20 and the cover member 10 may be aligned. In another embodiment, it is possible to determine the position of the panel member 20 through the driving degree of the roller unit 140 and to align the position of the panel member 20 and the cover member 10.

When the positions of the cover member 10 and the panel member 20 are aligned, the driving unit 130 may lift the second seating unit 120. At this time, when the second seating portion 120 is raised or lowered, a part of the panel member 20 may contact the adhesive member 40. In this case, it may come into contact with a part of the panel member 20 which is a part of the adhesive member 40 disposed on the flat part of the cover member 10. On the other hand, a portion of the adhesive member 40 disposed on the curved portion of the cover member 10 may not contact other portions of the panel member 20. In particular, the transfer member 160 may be arranged to be curved along the outer surface of the elastic member 123a, and the curved portion of the transfer member 160 may be spaced apart from the curved portion of the cover member 10. In addition, the transfer member 160 may prevent the elastic member 123a from rotating around one end of the elastic member 123a by having tension by the roller unit 140.

When the flat part of the cover member 10 and a part of the panel member 20 are combined, the relative position of the cover member 10 and the panel member 20 is fixed so that the cover member 10 and the panel member 20 It can prevent misalignment.

When the pump 152 is operated, gas may be injected into the volume variable part 123b through the pipe 151. In this case, the internal space of the volume variable part 123b may be increased by gas, and the outer surface of the volume variable part 123b may move from the initial position toward the elastic member 123a to contact the elastic member 123a. The distance from the center of the cross section perpendicular to the length direction of the volume variable part 123b to the inclined part of the elastic member 123a is from the center of the cross section of the volume variable part 123b to the curved part of the elastic member 123a By being smaller than the distance of, the variable volume portion 123b may first contact the bent portion (or inclined portion) of the elastic member 123a than the other portions of the elastic member 123a. In this case, the volume variable part 123b applies the inclined portion of the elastic member 123a to the inclined side of the pressure plate 122, and the inclined portion of the elastic member 123a is inclined with the pressure plate 122 It can be in contact with or close to the side.

When the injection part 150 continuously supplies gas into the volume variable part 123b, the inclined part of the elastic member 123a is on the inclined side of the pressure plate 122 or the flat part of the cover member 10. By doing so, it can no longer move. At this time, the volume variable portion 123b in contact with the inclined portion of the elastic member 123a may no longer move, and a position of the other portion of the volume variable portion 123b other than this may be variable. That is, the volume variable part 123b initially moves the same position of all outer surfaces, and in the above case, the position of a part of the volume variable part 123b is maintained as it is, and the other part of the volume variable part 123b is Only the position can be changed.

In the above case, the other part of the volume variable part 123b presses the elastic member 123a with the curved part of the cover member 10 as shown in FIGS. 4 to 6, and the elastic member 123a is a panel The member 20 may be pressed into the curved portion of the cover member 10. At this time, one end of the elastic member 123a may be rotated. In this case, the transfer member 160 is stretched to move like the elastic member 123a, or the roller unit 140 adjusts the tension of the transfer member 160 so that the transfer member 160 does not interfere with the movement of the elastic member 123a. It can work to reduce.

In this case, the end of the elastic member 123a may be separated from the elastic member fixing portion 123d. At this time, the end of the elastic member (123a) is separated from the elastic member fixing portion (123d) when the volume of the volume variable portion (123b) starts to change, or when the volume of the volume variable portion (123b) becomes more than a certain volume, the elastic portion It is also possible to depart from the reconsideration government (123d).

In the above case, the cover member 10 is sequentially coupled with the panel member 20 from the flat portion of the cover member 10 to the end of the curved portion of the cover member 10 as shown in FIGS. 4 to 6 can do. In this case, when the cover member 10 and the panel member 20 are combined from the flat portion of the cover member 10 to the curved portion of the cover member 10, bubbles, etc. between the panel member 20 and the cover member 10 This can be prevented from occurring.

When the combination of the panel member 20 and the cover member 10 is completed, the pump 152 may be operated to discharge the gas inside the volume variable part 123b to the outside through the pipe 151. At this time, the internal space of the volume variable part 123b is small, so that the initial state can be returned. In addition, the elastic member 123a may return to its original state by the restoring force. At this time, an end of the elastic member 123a may be fixed to the elastic member fixing portion 123d.

In this case, since the radius of curvature of the curved portion of the elastic member 123a is smaller than the radius of curvature of the curved portion of the cover member 10, the transfer member 160 may be separated from the panel member 20. In particular, the transfer member 160 is in a state in which the tension is maintained by the roller unit 140 to correspond to the outer surface shape of the second seating unit 120 for a certain amount or more, so when the volume variable part 123b returns to the initial state, The member 160 may be separated from the panel member 20 by moving the member 160 along the outer surface of the second seating portion 120.

Thereafter, the driving unit 130 may be operated to separate the second seating portion 120 from the first seating portion 110. At this time, even when the transfer member 160 is not separated from the panel member 20 when the volume variable part 123b returns to its initial shape as described above, the transfer member 160 according to the movement of the second seating portion 120 ) May be separated from the panel member 20. In addition, a portion of the transfer member 160 disposed on a flat portion of the cover member 10 according to the movement of the second seating portion 120 may be separated from the panel member 20.

When manufacturing of the display device is completed after the panel member 20 is coupled to the cover member 10 as described above, the display device may be separated from the first seating portion 110 and transferred to another location.

When the above process is completed, a new cover member 10 is placed on the first seating portion 110 and the panel member 20 is placed on the second seating portion 120 to repeat the above operation. can do.

Accordingly, the display device manufacturing apparatus 100 and the display device manufacturing method can manufacture a display device in which defects do not occur.

At this time, the first seating unit 110-1, the roller unit 140-1, the injection unit 150-1, the chamber, the vision unit, and the pressure control unit are the same as those described in FIGS. 1 and 2 or Since they are similar, detailed descriptions will be omitted.

The second seating part 120-1 may include pressing parts 121-1 and 122-1 and a shape variable part 123-1. At this time, since the pressing parts 121-1 and 122-1 are the same as or similar to those described in FIGS. 1 and 2, detailed descriptions will be omitted.

The shape variable portion 123-1 may include a volume variable portion 123b-1, an elastic member 123a-1, and a cushion portion 123c-1. At this time, since the elastic member 123a-1 and the cushion part 123c-1 are the same as or similar to those described in FIGS. 1 and 2, the following will be described in detail with the volume variable part 123b-1.

The volume variable part 123b-1 may be disposed between the body part 121-1 and the pressure plate 122-1. At this time, the variable volume part 123b-1 may be formed in the form of a film including an elastic material such as rubber, silicon, etc., and the volume variable part 123b-1 and the body part 121-1 have a space therein. Can be formed. Gas or fluid may be supplied to this space by the injection unit 150-1.

In this case, the adhesive member 40 may be disposed or disposed on the side of the cover member 10 or the panel member 20. After arranging the panel member 20 and the cover member 10 so as to face each other by driving the roller unit 140-1, the position of the panel member 20 and the cover member 10 is identified by the vision unit to determine the position of the panel member ( 20) and the position of the cover member 10 can be aligned.

When the panel member 20 and the cover member 10 are aligned with each other, the driving unit 130-1 is operated so that the first and second mounting portions 110-1 and 120-1 may be close to each other. . At this time, the roller unit 140-1 may maintain the tension of the transfer member 160-1 above a predetermined size.

As described above, when the first and second seating portions 110-1 and 120-1 reach a certain distance, the pump 152-1 operates and the volume variable portion ( 123b-1) and the body portion 121-1 may be supplied with gas. In this case, the shape of the volume variable part 123b-1 is variable, so that the pressure plate 122-1 can be moved toward the cover member 10. At this time, since the volume variable part 123b-1 may be changed to be the same or similar to each other on the front surface, the pressure plate 122-1 and the elastic member 123a-1 may move equally by a predetermined distance.

When the pressure plate 122-1 moves, the pressure plate 122-1 moves the transfer member 160-1 on which the panel member 20 is seated toward the cover member 10, thereby forming a flat portion of the cover member 10.

On the other hand, when the injection part 150-1 continuously supplies gas or fluid to the space between the volume variable part 123b-1 and the body part 121-1, it is pressurized by the flat part of the cover member 10. The movement of the plate 122-1 may be stopped, and the portion of the volume variable part 123b-1 in which the pressure plate 122-1 is disposed may no longer change in shape or position.

In this case, as gas or fluid is supplied, the shape or position of the volume variable portion 123b-1 in which the pressure plate 122-1 is not disposed may be changed. In this case, while the portion of the volume variable portion 123b-1 in which the pressure plate 122-1 is not disposed is variable, it may contact a portion of the elastic member 123a-1 to press the elastic member 123a-1.

Hereinafter, for convenience of description, the other end of the elastic member 123a-1 will be described in detail with a focus on a case in which the other end has a free end shape.

When the volume of the elastic member 123a-1 is variable, the position of the elastic member 123a-1 may not change initially due to the tension of the transfer member 160-1. Thereafter, when the shape of the elastic member 123a-1 changes by a certain degree or more, the elastic member 123a-1 rotates the other end of the elastic member 123a-1 based on one end of the elastic member 123a-1. By doing so, the transfer member 160-1 can be sequentially applied from the flat portion of the cover member 10 to the end of the curved portion of the cover member 10.

In the above case, the elastic member 123a-1 is partially moved and the shape of the elastic member 123a-1 is changed, so that the panel member 20 is disposed on the curved portion of the cover member 10. ) Can be attached. At this time, the panel member 20 may be sequentially attached to the adhesive member 40 from the flat portion of the cover member 10 to the end of the curved portion of the cover member 10 as described in FIGS. 3 to 4 above. have.

When the above process is completed, gas or fluid between the volume variable portion 123b-1 and the body portion 121-1 is discharged to the outside through the injection portion 150-1, and the volume variable portion 123b-1 Can be returned to the initial state. At this time, the transfer member 160-1 may be separated from the panel member 20 in response to a change in the shape of the volume variable part 123b-1 by maintaining a constant tension by the roller part 140-1.

Thereafter, the first seating portion 110-1 and the second seating portion 120-1 may be separated from each other by operating the driving unit 130-1 to raise and lower the first seating portion 110-1. At this time, the transfer member 160-1 is a panel member ( It is also possible to separate from 20).

After the panel member 20 is coupled to the cover member 10 as described above, the manufactured display device (not shown) may be separated from the first seating portion 110-1 and transferred to another location. In addition, after the new cover member 10 is disposed on the first seating portion 110-1 and the panel member 20 is disposed on the transfer member 160-1, the above process may be repeated.
